Aug. 29, 2012 — A NASA satellite captured a spectacular photo of what is now Hurricane Isaac from space, a nighttime view showing the then-tropical storm's clouds lit up by moonlight as it approached the U.S. Gulf Coast.
NASA's Suomi-NPP weather tracking satellite recorded the amazing nighttime photo of Isaac just after midnight on Tuesday (Aug. 28). The bright city lights of New Orleans, Houston and Tampa, Fla., can be easily identified, but the photo also includes lights from cities all along the Gulf Coast, Florida and the southeast U.S. coast.
"The image was acquired just after local midnight by the VIIRS 'day-night band,' which detects light in a range of wavelengths from green to near-infrared and uses light intensification to enable the detection of dim signals," NASA officials explained in an image description. "In this case, the clouds of Isaac were lit by moonlight."
